Answer:

Area: 5π/2 in²

Perimeter: (3π+2) in

step-by-step explanation:

Area =

larger semicircle + small semicircle

= ½(pi × r1²) + ½(pi × r2²)

r1 = 2 in

r2 = 2/2 = 1 in

Area:

½(pi × 2²) + ½(pi × 1²)

= 2pi + ½pi

= 5pi/2 in²

Perimeter:

½(2pi × r1) + ½(2pi × r2) + r1

½(2pi × 2) + ½(2pi × 1) + 2

2pi + pi + 2

3pi + 2

Answer:

The most reasonable is 2 h

Step-by-step explanation:

If you see the graph is decreasing in hours while is increasing in years. When a person is 45 years the amount of daily physical activity is 3 hours, so a person that is 50 years needs to do less than 3 hours a day and the only option less than 3 hours is 2 hours.

Answer:

The first one is a right triangle.  The second one is C. (13,9)

Step-by-step explanation:

For each ordered pair, go over first, then up.  For the first question, if all points are plotted, it makes a right triangle.

With the second question, the point must be the same distance from Q as P is already.  That's 3 lines over and 7 lines up and down.  It could stay at (__,9), so 3 spaces over is (13,9).  

To prove the converse of the Pythagorean theorem, it must be assumed that the Pythagorean theorem is true. This assumption is fundamental to the proof. Option A is correct answer.

The proof of the converse of the Pythagorean theorem.

To prove the converse of the Pythagorean theorem, it is important to start by assuming that the Pythagorean theorem itself holds true.

Therefore, option A is the correct answer: It must be assumed that the Pythagorean theorem is true.

This fundamental assumption is crucial since the converse states that if the sum of the squares of two sides of a triangle is equal to the square of the third side, then the triangle is a right triangle.

This is a direct implication assuming the Pythagorean theorem's validity.

An essential part of a mathematical proof, especially in geometry, involves using established theorems and logical deductions.

It's also worth mentioning Euclid's proposition that states, "Any two sides of a triangle are together greater than the third side." While this proposition is relevant to the properties of triangles, it is not a component of the proof for the converse of the Pythagorean theorem.

Answer:

y = - [tex]\frac{1}{4}[/tex] x - 3

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (0, - 3) and (x₂, y₂ ) = (4, - 4) ← 2 points on the line

m = [tex]\frac{-4+3}{4-0}[/tex] = - [tex]\frac{1}{4}[/tex]

y = - [tex]\frac{1}{4}[/tex] x - 3 ← equation of line

Answer:

undefined.  

Step-by-step explanation:

so there is a point at the origin, and from there there are two rays coming off it.  One goes along the positive x axis, so it goes straight right, then the other goes through point (0,1).  That point is right above the origin.  So it makes an l shape.  what sort of polygon could you fit into the corner of an L?  Well, a square or rectangle, and the corners of a square and rectangle are all 90 degrees is theta.

Now it wants tan of 90 degrees.  tangent is sine divided by cosine, so let's find those.

sine of 90 is the y value on the unit circle at 90 degrees.  Since the unit circle has a radius of 1 then when it points straight up or down the y value is either 1 or -1 respectively.  Similarly cosine is 1 when pointing to the right, at 0 degrees or 360 degrees, and -1 at 180 degrees.  For sine straight up is of course 90 degrees and down is 270 degrees.

Now, sine of 90 is 1 and cosine of 90 is therefore 0.  so now we want sine divided by cosine.  this is 1/0.  Well you can't divide by 0, so it is undefined.

The length of the radius, r, is 21 cm. The correct answer is **c. 21 cm**.

Here's why:

- The circumference of a circle is calculated by the formula C = 2πr, where C is the circumference and r is the radius.

- We are given that the circumference of circle O is 42π.

Substituting the given value into the formula:

42π = 2πr

Dividing both sides by 2π:

r = 42π / 2π

Simplifying:

r = 21

Therefore, the length of the radius, r, is 21 cm.

Options a, b, and d are incorrect because they either involve taking the square root of the circumference directly (invalid formula for radius) or miscalculating the result of the division.
